WATER-Moron.

To all whom t may concern:

Be it known that I, HERBERT H. RAM- frriUN, a citizen oi the UnitedStates, residing at Milwaukee, in the county of Milwaukee and State ofWisconsin, have in vented new and useful improvements in 1llaterMotors,oi which the following is a specification.

This invention relates to water motors and more particularly to therotor construction, the principal obj ect of the invention is to providea water motor, the rotor of which can be accurately constructed at asmall cost with the resultant decrease in cost oit the water motor as awhole.

A further object of the invention is 'to form the blades with acentrally arranged rib arcuate shaped in cross section for defiectingthe water emerging from the nozzle to opposite sides of the rotor.

The invention consists in the features oi' construction, combination,and arrangement of parts, hereinafter fully described and claimed,reference being had to the accomA panying drawings, in which:

Figure l is a vertical section through the water motor.

Fig. 2 is a side elevation thereoli.

The remaining iigures are detail sections showing the blades as attachedto the disk of the rotor.

Referring to the drawings, the numeral l designates a rectangular casingin which is centrally arranged a rotor that comprises a disk 3 and aseries of blades l attached Each blade has a longi tudinal rib eupstruck from its bod;7 throughout the length of the working facethereof and standing at the transverse center of the same in line withthe disk, so that water falling thereon is to an extent divided andcaused to pass to the sides of the disk.

Secured to the top wall lof the easing and projecting therethrough is anozzle having its outletv end 6 arranged tangentially to the peripheryof the disk so that the energy of the water issuing from the nozzle willact in the proper direction upon the blade. rlhis nozzle has a swivelconnection 7 with a hose line 8 shown in this particular instance asmaking connection with a spigot.

The disk is provided in its edge with a series of notches substantiallyradial there- Copies of this patent may be obtained for Specification ofLetters Patent.

to and opening through the periphery there of as best seen at 15 in Fig.3, and with these notches are engaged the inner ends of the blades 4, byinserting the inner ends orn the ribs i thereof into said notches asalso best seen in Fig. 3. Each blade is by prei2N erence dishedlongitudinally a little, and perhaps also dished a triiie transversely,although in this direction the dishing is so little that the blade maybe said to be substantially flat excepting for the rib, and theupstruckrib is arched as best seen in Fig. el. it is the inner end ofthis arched rib that is inserted into the notch, and as the crown ot'the arch curves longitudinally to conform with the dish of the blade,the notch will have a corresponding longitudinal curvature as best seenin Fig. 3. VThis speciiic detail of construction makes the connectionbetween each blade and the disk a closer one than the blade and its ribwere perfectly straight and the slot was also straight. Furthermore,owing to the conliguration of the rib, a portion oit the inner surfaceof the walls of the latter embraces the sides et' the disk forpreventing lateral movement while the frictional engagement between therib and the slot will prevent outward movement of the blade. y

As the pressure of the water issuing from the nozzle acts at a tangentto the periphery `of the disk, it will be seen that there is very littlestress tending` to dislocate the blades in a radial direction with theresult that only the centrifugal force has to be taken care of.

Having described the invention what is claimed is:

in a water motor, the combination with a disk having` cut through it atits periphery a series of substantially radial notches, of a series. oi'blades each dished slightly throughout its length and having at itstransverse center an upstruck rib whose arch is inserted in one of saidnotches, all portions of the blade on opposite sides of its rib beingsubstantially fiat transversely, for the purpose set forth.

In testimony whereoi2 I affix my signa ture in presence of twowitnesses.
